Asymmetric incremental sheet forming (AISF) could significantly reduce costs incurred by the fabrication of complex industrial components with a minimal environmental impact. The AISF experiments were carried out on commercially pure titanium (Ti-Gr2), Timetal (15-3-3-3) alloy, and Ti-6Al-4V (Ti-Gr5) alloy. A special testing geometry was used to characterize the titanium alloys properties from ...

Because the forming area involved in traditional reverse multistage incremental is only located inside model, sheet-metal thinning rate relatively large. Particularly, straight-wall parts with a narrow internal space cannot be formed using forming. Therefore, negative that extrudes sheet from forward and side of part proposed this paper. In method, firstly, auxiliary surface generated to divide...

Incremental sheet forming (ISF) process show a great potential in the manufacturing of small series production or prototype development parts. One metal process, where contact between punch and is single point, known as point incremental (SPIF). The part manufacture with simple tool, punch, that performs combined movements on vertically horizontally directions. paper introduces study regarding ...

The main purpose of this research work is to study the forming limit and fracture behaviour AZ31 magnesium alloy, as well improve formability surface roughness parts formed using warm incremental sheet (ISF) process. For ISF process, Mg alloy sheets were used. Initially, Taguchi orthogonal L27 arrays used design experiments, a framed multi-objective optimization problem was solved grey-fuzzy me...

in recent years, in order to reducing die design and manufacturing costs, multi point forming technique has gained an increasing interest because of its high flexibility. in this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. in this paper, the fundamental principles of multi-point forming was described and the possib...
